| description | Pb-based piezoelectric ceramics cause serious Pb pollution during manufacturing, Pb-free niobate-based piezoelectric ceramics have strong ferroelectricity and high Curie temperatures, rendering them more suitable for making ceramics. For this reason, this article studies the preparation process, structure, and modification of alkali metal niobate Pb-free piezoelectric ceramics by the solid-state method to improve the environmental protection of the prepared materials and the performance of piezoelectric ceramics. The 0.94(K0.5Na0.5)NbO3-0.06LiNbO3 lead-free piezoelectric ceramics were prepared, study the performances and structural transformations of Pb-free piezoelectric ceramics mixed with other metal materials after adding alkali metal niobates. In addition, their influence on the microscopic morphology and electrical properties of KNN-based ceramics is studied, the optimal compositions and sintering temperatures of the Pb-free alkali metal niobate piezoelectric ceramics were investigated. |
